Brilliant from start to finish. From a quote late last year I contacted the original and he came that day to give me a new quote. Marcin got me a fab deal. Top lad. The fitters were friendly and efficient and everything looks amazing. I was that impressed with the work done as its substantial expense! Highly recommend.

Trustpilot

I normally do not bother with reviews but this one is well deserve. From challenging and complex design to exceptional delivery Grabex have delivered both prearranged glazing phases of our own little grand design project. Service, and what most important huge level of patience to work with us is just much appropriated. We are very pleased to have agreed lead-time delivered what that we did not experienced from other contractors working on the project. Product is fantastic, looks better than in showroom, joinery shop visit was educating and very interesting - never been to factory. We can now enjoy new glazing - let’s hope now rest of trades will follow. Big Thank you for all involved.

We love meeting our clients in our showroom, but due to the current conditions we ask all our visitors to book their Orpington showroom visit in advance. Showroom visits are available by appointment only, and if you choose to visit without making prior appointment you might be turned away or asked to wait whilst the other meeting is taking place.

The health and safety of our staff and customers is paramount and several procedures are in place. We are also asking all visitors to our showroom to wear face masks, and if you forget one you can use those available at our showroom in exchange for a small donation towards our fundraising campaign for our local Demelza Hospice for Children.
